Sesquiterpene lactone glycosides from Arnica longifolia
Planta Medica 65(2) (1999)
153-156
Flowers of Arnica longifolia were investigated for the occurrence of sesquiterpene lactone glycosides. A mixture containing the two isomeric 11α,13-dihydro- and 11β,13-dihydro-4H-tomentosin glucosides, previously isolated from A. amplexicaulis and A. mollis, together with the two isomeric 11α,13-dihydro- and 11β,13-dihydro-4H-carabrone glucosides were found in A. longifolia. All carbon and proton shifts of the glycosides could be assigned by their 2D-COSY and 2D-HETCOR spectra and spectroscopy of their respective aglycones, obtained via enzymatic hydrolysis.
